- Battery capacity: Shows the residual capacity of the batteries in digital and bar graph form.
- Minimum value indicator: The row of white pixels in the bar display represent the lowest voltage
which occurred during the flight. If the minimum value is significantly lower than the actual volta-
ge, this may indicate unsuitable or defective batteries.
- Total current output: Displays your model's actual current drain.
- Output voltage: Voltage display for both power circuits A and B.
- Current output, Batt. 1 and Batt. 2: Current output of the two batteries in bar graph form.
The RF - Flight Recorder display is accessed by briefly and simultaneously pressing buttons I and
II on the SensorSwitch:
Antenna Fades: - Spektrum, Futaba, M-Link: This item displays the lost data packets for the indivi-
dual receivers.
- HoTT and Jeti: This item displays the number of switching events between the
receivers.
Lost Frames: This value shows how many occasions none of the connected receivers was able
to supply a valid data packet.
Holds: This value is incremented when none of the connected receivers is able to supply
a valid signal for a period longer than 250 ms. When this occurs, the servos move
to the Hold or Fail-Safe positions stored in the backer.
The Power-Flight Recorder display can be accessed by briefly and simultaneously pressing but-
tons I and II on the SensorSwitch a second time:
This Flight Recorder enables you to monitor all data relating to current and batteries.
- Min. Voltage: This is the lowest value to which your battery voltage fell during the flight.
- Max. Current: The highest current which was drawn from each battery during the flight.
- Consumption: This item shows the energy consumed since the system was last switched on. The
value is erased when you switch the system off.
Note: it is extremely rare for the maximum current and / or energy consumption of both batte-
ries to be identical. In fact, the discrepancy is proof that the backer exhibits "genuine redun-
dancy", i.e. it contains two systems which work entirely independently of each other. Although
we go to great lengths to match the integral regulators accurately to each other, there are al-
ways minor manufacturing tolerances in the components, hence the difference. Only non-re-
dundant systems drain the batteries equally.
